and fill in the blanks.
Beware, that if it is standard on the TM, then do not include it as an extra when filling in the blanks. Furnace, fridge, and so forth are already figured in. AC, Awning, etc, need to added to the standard model.
Seens to be a pretty good deal, if it is good to excellent condition.
